Uses of OutputChannel in org.apache.druid.frame.processor

Methods in org.apache.druid.frame.processor that return OutputChannel
Modifier and Type	Method	Description
`static OutputChannel`	OutputChannel.`immediatelyReadablePair(WritableFrameChannel writableChannel, MemoryAllocator frameMemoryAllocator, ReadableFrameChannel readableChannel, int partitionNumber)`	Creates an output channel pair, where the readable channel is usable before writing is complete.
`OutputChannel`	OutputChannel.`mapWritableChannel(Function<WritableFrameChannel,WritableFrameChannel> mapFn)`
`static OutputChannel`	OutputChannel.`nil(int partitionNumber)`	Create a nil output channel, representing a processor that writes nothing.

`OutputChannel`	ComposingOutputChannelFactory.`openNilChannel(int partitionNumber)`
`OutputChannel`	FileOutputChannelFactory.`openNilChannel(int partitionNumber)`
`OutputChannel`	OutputChannelFactory.`openNilChannel(int partitionNumber)`	Create a non-writable, always-empty channel pair tagged with a particular partition number.
`static OutputChannel`	OutputChannel.`pair(WritableFrameChannel writableChannel, MemoryAllocator frameMemoryAllocator, Supplier<ReadableFrameChannel> readableChannelSupplier, int partitionNumber)`	Creates an output channel pair, where the readable channel is not usable until writing is complete.
`OutputChannel`	OutputChannel.`readOnly()`	Returns a read-only version of this instance.
`static OutputChannel`	OutputChannel.`readOnly(Supplier<ReadableFrameChannel> readableChannelSupplier, int partitionNumber)`	Creates a read-only output channel.
`static OutputChannel`	OutputChannel.`readOnly(ReadableFrameChannel readableChannel, int partitionNumber)`	Creates a read-only output channel.

Methods in org.apache.druid.frame.processor that return types with arguments of type OutputChannel
Modifier and Type	Method	Description
`List<OutputChannel>`	OutputChannels.`getAllChannels()`	Returns all channels.
`List<OutputChannel>`	OutputChannels.`getChannelsForPartition(int partitionNumber)`	Returns channels for which `getPartitionNumber()` returns `partitionNumber`.

Method parameters in org.apache.druid.frame.processor with type arguments of type OutputChannel
Modifier and Type	Method	Description
